Region-based power grid generation through modification of an initial power grid based on timing analysis

Abstract

Embodiments for power generation include defining a power tile within a power distribution network having a grid of power rails, the power tile having logic gates, and applying an initial power grid pattern from a plurality of power grid patterns for the power tile such that initial power grid pattern relates to timing characteristics of the logic gates of the power tile. The power grid patterns each have a different number of connectors connecting one power rail to another power rail in the grid of power rails. A subsequent power grid pattern is selected from the power grid patterns for the power tile such that the subsequent power grid pattern meets a threshold condition for the timing characteristics of the logic gates of the power tile. The timing characteristics for the logic gates are determined based on a voltage drop associated with the subsequent power grid pattern.
